说明：  配置GTH ip的例子工程，选用7 series 芯片的GTH 113quad的四个通道，在程序中每个链路利用自己的恢复时钟进行数据解码，所以四个通道可以各自独立运行；成功工作在2.54Gb/s的链路状态，长时间（>24小时）的测试，误码率一直为0.(The GTH ip example project is configured with four channels of the GTH 113quad of the 7 series chip. Each link in the program uses its own recovery clock for data decoding, so the four channels can operate independently; the successful operation is at 2.54Gb/ The link state of s, long time (>24 hours) test, the bit error rate has been 0.)

说明：  使用VHDL实现的LED-80分组密钥，相对于其它密钥具有硬件实现面积更小的特点(vhd code of a lightweight block cipher LED-80)

DDS在现在运用月来越广泛，在相对带宽、频率转换时间、相位连续性、正交输出、高分辨力以及集成化等方面都远远超过了传统频率合成技术所能达到的水平，为系统提供了优于模拟信号源的性能。利用DDS技术可以很方便地实现多种信号。在FPGA上实现的DDS-DDS now to the use of more extensive relative bandwidth, frequency conversion time, phase continuity, quadrature output, high-resolution and integration, and other aspects far more than the traditional frequency synthesizer technology can achieve the level To provide a superior analog signal source performance. DDS technology can be used very easily to a variety of signal. FPGA Implementation of DDS

7段数码显示译码器设计7段数码是纯组合电路，通常的小规模专用IC，如74或4000系列的器件只能作十进制BCD码译码，然而数字系统中的数据处理和运算都是二进制的，所以输出表达都是十六进制的，为了满足十六进制数的译码显示，最方便的方法就是利用译码程序在FPGA/CPLD中来实现。例子作为七段译码器，输出信号LED7S的7位分别接数码管的7个段，高位在左，低位在右。例如当LED7S输出为“1101101”时，数码管的7个段g、f、e、d、c、b、a分别接1、1、0、1、1、0、1；接有高电平的段发亮，于是数码管显示“5”。-7 digital display decoder design 7 Digital is pure combinational circuits, usually of small-scale dedicated IC, such as 74 or 4000 Series devices can only be used to decimal BCD decoder, but digital systems in the data processing and computing are binary, so the output expression are hexadecimal, and hexadecimal number in order to meet the needs of the decoding shows that the most convenient way is to use decoding process in FPGA/CPLD in to achieve. Seven-Segment decoder as an example, the output signal of the seven were LED7S access digital pipe 7 above, high in the left, low in the right. For example, when LED7S output as
